Definitions

  • This invention relates to motor vehicles and in particular to a motor vehicle plastic body panel.
  • a motor vehicle plastic body panel comprising a plastic window pane and an opaque plastic panel defining an outer surface of part of the motor vehicle wherein the plastic window pane is moulded as an integral part of the motor vehicle plastic body panel.
  • the plastic window pane and the opaque plastic panel may be formed by one of a co-moulding process and an over moulding process.
  • the plastic window pane may have an outer peripheral border and the outer peripheral border of the plastic window pane may be embedded within the opaque plastic panel.
  • the opaque plastic panel may have an aperture defining a window frame and an inner peripheral edge of the outer peripheral border of the plastic window pane may be defined by the window frame.
  • a motor vehicle having at least one plastic body panel constructed in accordance with said first aspect of the invention.
  • a method of manufacturing a one piece motor vehicle plastic body panel having a plastic window pane and an opaque plastic panel having an outer surface defining in use part of an exterior surface of a motor vehicle comprising forming the plastic window pane from a first plastic material and injecting a second plastic material into a mould in which the plastic window pane is located so as to embed an outer peripheral border of the window pane in the second plastic material and form the opaque plastic panel.
  • Forming the plastic window pane may comprise injecting the first plastic material into the mould to produce the plastic window pane before injecting the second plastic material into the mould to form the opaque plastic panel.
  • forming the plastic window pane may comprise producing a plastic window pane to a required size and shape from the first plastic material and placing the plastic window pane in the mould before injecting the second plastic material into the mould to form the opaque plastic panel.
  • the opaque plastic panel has a window frame portion in which the outer peripheral border of the plastic window pane is embedded.
  • FIG. 1 is a schematic side view of a motor vehicle according to a second aspect of the invention having a pair of plastic body panels according to a first aspect of the invention
  • FIG. 2 is a cross-section along the line X-X on FIG. 1 .
  • a motor vehicle 10 having a body structure including two rear plastic body panels 11 of which only the left-hand side one is visible.
  • the motor vehicle 10 has a front end ‘F’ and a rear end ‘R’ and four road wheels 14 at least two of which are driven by a drivetrain of the motor vehicle 10 .
  • the motor vehicle 10 includes a pair of front doors 13 of which only the left-hand side one is visible and various other external body panels such as a trunk lid, a bonnet, a pair of front wings 15 of which only the left-hand side one is visible and a roof 19 all of which may be made from plastic.
  • Each of the rear plastic body panels 11 comprises an opaque plastic panel portion 12 having an aperture defining a window frame 12 f and a fixed, immoveable plastic window pane 20 formed as an integral part of the rear body panel 11 .
  • the opaque plastic panel 12 has an inner surface 16 and an outer surface 17 , the outer surface 17 defining part of an outer surface of the motor vehicle.
  • the plastic window pane 20 has an outer periphery 21 that is embedded in the opaque plastic panel 12 such that an outer peripheral border of the plastic window pane 20 lies within the opaque plastic panel 12 .
  • the outer peripheral border of the plastic window pane 20 corresponds to the part of the plastic window pane 20 that is embedded in the opaque plastic panel 12 and an inner peripheral edge of the outer peripheral border of the plastic window pane 20 is defined by the window frame 12 f.
  • the plastic window pane 20 can be made from any suitable transparent plastic having good optical clarity and scratch resistance.
  • One such plastic material is polycarbonate but the invention is not limited to the use of polycarbonate.
  • the plastic window pane 20 is transparent it is not necessarily clear, it could be tinted depending upon it location.
  • the opaque plastic panel 12 is moulded over the plastic window pane 20 so that no seal is needed therebetween.
  • Various materials could be used for the opaque plastic panel including but not limited to ABS, a reinforced plastic such as fibre reinforced polypropylene and other injection mouldable plastics having sufficient thermal stability and strength for use as a motor vehicle body panel.
  • the rear body panel 11 can be manufactured by several methods, in a first method, a two shot co-moulding process is used. In this process a first plastic material is injected into a first cavity in a mould to form the plastic window pane 20 and then a second plastic material is injected into a second cavity in the mould. The second plastic material flows around the outer peripheral border of the window pane 20 so as to embed it therein and also flows in the mould cavity to produce the required inner and outer surfaces 16 and 17 of the opaque plastic panel 12 .
  • the two plastic materials could be the same basic plastic but having different properties the most significant difference being that one is transparent and the other is not.
  • Advantages of the use of a co-moulding process include faster cycle time due to not having to transfer the part to another tool and the reduction of handling errors in between shots.
  • the window pane is manufactured to a desired shape and size by a first process, which could be an injection moulding process.
  • the sized and shaped plastic window pane is then placed in a mould into which a plastic material is injected to form the opaque plastic panel 12 .
  • the mould is shaped to form the inner and outer surfaces 16 and 17 of the opaque body panel 12 .
  • Such a process is sometimes referred to as ‘over moulding’ or ‘insert moulding’.
  • One advantage of the invention is that a one piece plastic body panel is formed in an economical manner.
  • a further advantage is that no seals are required between the plastic window pane and the opaque plastic panel because the two components are moulded together.
  • plastic body panel is a rear body panel
  • other potential applications include, for example and without limitation, tailgates, front and rear windscreens, fixed sunroofs and/or panoramic roofs.
  • Some advantages of the invention are that it results in a lightweight body panel construction due to the use of plastic for entire body panel, a reduced number of components and reduced cost (e.g. clips and secondary trim panels may not be required) and the single piece plastic exterior panel and window results in a reduction of the number of parts to be assembled and hence a reduction in assembly time.
